高温健康风险预警来了

Core Viewpoint - The establishment of the first national-level high-temperature health risk warning system by the National Disease Control and Prevention Bureau and the China Meteorological Administration aims to effectively address health risks associated with climate change through an integrated early warning mechanism [1][2]. Group 1: High-Temperature Health Risk Warning System - The high-temperature health risk warning system is categorized into five risk levels: low risk, moderate risk, high risk, very high risk, and extreme risk, with the latter three levels being publicly communicated [1]. - The classification standard is based on the analysis of excess mortality rates related to cardiovascular and respiratory diseases in response to high temperatures [1][2]. Group 2: Regional Risk Assessment - The high-temperature health risk warning is oriented towards population health risks and utilizes relative temperature threshold methods to calculate risk thresholds for different regions, enhancing the precision of health risk identification in atypical high-temperature areas [2]. - The system incorporates historical observation data from 2,400 meteorological stations over the past decade to create a national grid with a resolution of 5 kilometers for risk assessment [2]. Group 3: Future Developments - Starting from May 2024, a specialized technical team will be formed to promote the integration of health and meteorological technologies, transitioning health meteorological risk warnings to a more quantitative and precise approach [2]. - The meteorological department plans to utilize the "Tianhe" system to disseminate warning information through multiple channels, including the national warning release system and social media, to enhance public awareness and response to high-temperature health risks [2].
